Heliconia plant named ‘Lars’

ABSTRACT

A new cultivar of  Heliconia  plant named ‘Lars’ that is characterized by a compact habit and small orange flowers that bloom throughout the entire year.

Botanical classification: Heliconia psittacorum.

Variety denomination: ‘Lars’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofHeliconia plant botanically known as Heliconia psittacorum andhereinafter referred to by the cultivar name ‘Lars’.

The new cultivar was discovered as a naturally occurring whole plantmutation in a cultivated area of Enkhuizen, The Netherlands. The exactparent plant is unknown. The cultivar ‘Lars’ was discovered by theinventor in 1999 as a single plant.

Asexual reproduction first occurred when rhizomes of the new cultivar‘Lars’ were propagated in 2000 in Enkhuizen, The Netherlands. Since thattime, under careful observation, the unique characteristics of the newcultivar have been uniform, stable and reproduced true to type insuccessive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the newHeliconia cultivar ‘Lars’. These traits in combination distinguish‘Lars’ as a new and distinct cultivar apart from other existing knownvarieties of Heliconia.

-   -   1. Heliconia ‘Lars’ exhibits compact growth.    -   2. Heliconia ‘Lars’ exhibits orange flowers.    -   3. Heliconia ‘Lars’ exhibits small flowers.    -   4. Heliconia ‘Lars’ exhibits flowers that bloom throughout the        entire year.

The closest comparison cultivar is the Heliconia species, Heliconiapsittacorum sp. The new cultivar ‘Lars’ is distinguishable fromHeliconia psittacorum sp. by the following characteristics:

-   -   1. Heliconia ‘Lars’ exhibits a more compact habit.    -   2. Heliconia ‘Lars’ exhibits smaller flowers.    -   3. Heliconia ‘Lars’ exhibits flowers that bloom throughout the        entire year.

Plants of the species only bloom in summer.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits ofHeliconia ‘Lars’. The plant in the photograph shows an overall view of a4 month old plant. The photograph was taken using conventionaltechniques and although colors may appear different from actual colorsdue to light reflectance it is as accurate as possible by conventionalphotographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Heliconia cultivarnamed ‘Lars’. Data was collected in Enkhuizen, The Netherlands from 4month old glass greenhouse grown plants in 25 cm. diameter containers.The time of year was Fall and the temperature was kept at 22° Centigradeduring the day and 20° Centigrade at night. The light level was naturaloutdoor light. The soil Ph was 5.8. Color determinations are inaccordance with The Royal Horticultural Society Colour Chart 2001edition, except where general color terms of ordinary dictionarysignificance are used. The growing requirements are similar to thespecies. ‘Lars’ has not been tested under all possible conditions andphenotypic differences may be observed with variations in environmental,climatic, and cultural conditions, however, without any variance ingenotype.
